Helpful answers
Questions, answered.
What does the 640B listing name identify?
640B is the reference used in this store's product link. Match the full model and version printed on your device before choosing instructions or accessories; do not identify hardware from its screen alone.
Can I use it to check that my baby is well?
No. Sounds and display values do not reliably show your baby's wellbeing. If movements reduce, stop or change from their usual pattern, contact your midwife or maternity unit immediately. Do not wait for a device reading or store-support reply. Read NHS guidance (opens in a new tab).
Where can I find the matching instructions?
A confirmed final manual for this listing is not available to download here. Request instructions for your exact unit, including the label model and version. TX-series instructions are not a substitute.
What should I confirm before ordering?
Ask us to confirm the full device label, probe specification, power requirements, package contents and instructions for your destination. Product-reference images do not establish the contents of your order.
Which option should I select?
Select your Delivery Area. This is a regional option, not a probe specification or a list of included accessories. Confirm the exact device version, package contents and suitability for your market before ordering. Ask our team if you are unsure about compatibility.
Where can I find shipping and return information?
Read our shipping policy and refund policy for the store's current terms.
